Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the sweet milk and eggs, mixing well.
Sift together the flour and baking powder, then gradually add to the mixture.
Stir in the vanilla extract.
Bake the layers
Divide the batter into 4 thick layers and bake until a toothpick comes out clean.
Make and spread the frosting
For the frosting, boil 1 cup of sugar with enough water to dissolve it until thick.
While hot, pour the syrup over the beaten egg white, stirring briskly until thick.
Add the grated chocolate and spread the frosting over the cake immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb.
- Sugar
- Sweetens the cake and, creamed with butter, helps hold air for lift.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- All-purpose flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Baking powder
- Releases gas in the oven, helping the layers rise and turn light.
- German sweet chocolate
- Adds chocolate flavour and body to the frosting.
The step that matters
Pouring the hot syrup and spreading the frosting. Hot sugar syrup poured over beaten egg white cooks and thickens it into a glossy, fluffy icing as it cools. The frosting sets quickly, so it must be stirred until thick and spread on the cake immediately, before it stiffens and cannot be spread.
